Description

Technical Field

[0001] This utility model belongs to the field of building door and window technology, specifically relating to a prefabricated window frame. Background Technology

[0002] Prefabricated window frames are structural components widely used in prefabricated buildings, primarily installed in the exterior walls of prefabricated structures. Unlike traditional on-site window frame installation, prefabricated window frames are typically prefabricated in a factory and integrated with the exterior wall panels, pre-installed into the prefabricated components, and directly connected to the main structure during on-site installation. The integrated prefabrication of prefabricated window frames with exterior wall panels and insulation materials effectively reduces on-site construction steps and improves construction efficiency. Common materials for prefabricated window frames include aluminum alloy, PVC, and steel subframes. Aluminum alloy window frames are lightweight, sturdy, and resistant to deformation, and offer various surface treatments, making them suitable for most prefabricated buildings. Prefabricated window frames are installed via pre-embedded installation, effectively avoiding installation gaps between the frame material and the wall opening, enhancing the airtightness and waterproofing of the window joint, while also meeting the building's insulation requirements.

[0003] Existing prefabricated window frames are mostly filled with a single layer of fireproof sealant, which is prone to cracking and failure in a fire (fire resistance limit <1h); the window frame is fixed to the wall by welding or bolts, and the on-site construction time is >2 hours per window; and the glass is usually rigidly connected to the window frame, which leads to stress concentration under wind load and a glass breakage rate of >15%; traditional sealing strips form a smoke channel after high-temperature carbonization.

[0004] Therefore, this utility model provides a prefabricated window frame to solve the problems mentioned in the background art. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a prefabricated window frame. By setting fireproof sealing strips, fireproof gel layers and fireproof grooves, the fire resistance limit of this fireproof structure is significantly improved. Since this solution adopts multi-modular interfaces, the assembly efficiency is significantly improved. By setting fireproof gel layers, it expands in volume when exposed to fire, reducing the risk of glass breakage and preventing the fire from spreading further.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated window frame includes a window frame body, glass interlayers, fireproof channels, assembly channels, and a buffer layer. The window frame body is shaped like a window frame, the assembly channels are formed inside the window frame body, multiple glass interlayers are fixedly connected to the assembly channels, two fireproof channels are arranged opposite each other in the cavity of the window frame body, and the buffer layer fills the gap between the glass interlayers and the fireproof channels.

[0008] Further specifying, the fireproof groove includes a ceramic fiber mesh, the ceramic fiber mesh being filled with an intumescent fireproof gel layer, and the ceramic fiber mesh covering the outside of the fireproof gel layer to form a skeleton reinforcement layer. This structural design, by incorporating the intumescent fireproof gel layer, allows it to expand by 300% in volume upon exposure to fire, filling the cavity and preventing further spread of fire.

[0009] Further specifying, the assembly slot is provided with a dovetail guide groove, which extends along the length direction of the window frame.

[0010] Further specifying, the buffer layer includes a gradient density silicone layer and a shape memory alloy support, wherein the shape memory alloy support is embedded in the silicone layer.

[0011] Further specified, the density of the gradient density silicone layer is from 80 kg / m³. 3 Increase to 200 kg / m 3 .

[0012] Further specifying, the bottom of the glass interlayer is connected to multiple fireproof sealing strips, the outer layer of which is an expanded graphite layer and the inner layer is a fluororubber layer.

[0013] Further, it also includes prefabricated wall panels, with the assembly groove coupled to the prefabricated wall panels.

[0014] Furthermore, the main body of the window frame is made of aluminum alloy profile, and the wall thickness of the aluminum alloy profile is ≥2.5mm.

[0015] The beneficial effects of this utility model are:

[0016] This utility model significantly improves the fire resistance limit by setting fireproof sealing strips, fireproof gel layers, and fireproof grooves. Because this solution adopts multi-modal interfaces, the assembly efficiency is significantly improved. By setting fireproof gel layers, it expands in volume when exposed to fire, reducing the risk of glass breakage and preventing the fire from spreading further.

[0017] In summary, this utility model combines the passive protection of the fireproof groove with the active deformation of the buffer layer, solving the problem that traditional window frames cannot simultaneously achieve fire resistance and earthquake resistance. By setting the assembly groove and dovetail guide groove, the installation efficiency and locking tightness are significantly improved. The buffer layer absorbs high-frequency vibrations by setting a silicone layer, and the shape memory alloy bracket resists low-frequency displacement, reducing the probability of glass resonance.
